Table 2. Parameters from a mixed model of proportion of eggs normally fertilized across different sperm concentration in mussels, fitted using a Bayesian approach. Shown are posterior means and the 95% highest posterior density (HPD) intervals for (a ) random effects of measurement block (V block), male identity (V male), female identity (V female), specific combinations of males and females (V male × female), and specific environment (Ve ; residual variance) and (b ) fixed effects of population (3 levels; Geelong as the reference), body condition, gamete age (minutes), sperm concentration (continuous variable fitted both as a as linear and quadratic term), density of the male, density of the female, and their interactions with each other and with sperm concentration.
